### Simple, thread safe, buffer allocator in Rust

```rust

fn main() {

    let mut bytes: [u8; 25] = [0; 25];

    for n in 0..bytes.len() {

        bytes[n] = (n % 255) as u8;

    }

    let memory = Buffer::init_from_bytes(&mut bytes);

    println!("buffer size: {}", memory.len());

    let bytes1 = memory.alloc(12);

    if let Some(bytes1) = bytes1 {

        println!("bytes1 at-1: {}", bytes1[1]);

    }

    let bytes2 = memory.alloc_mut(10);

    if let Some(bytes2) = bytes2 {

        println!("bytes2 at-0: {}", bytes2[0]);

        bytes2[0] = 255;

        println!("bytes2 at-0 [after=255]: {}", bytes2[0]);

    }

    let bytes3 = memory.alloc(20);

    assert_eq!(None, bytes3);

}

```
